Description

Technical area

The invention relates to an application device for screen protection films, in particular an application device for screen protection films to be applied in two stages.

State of the art

The rapid development of display devices is due to their needs in everyday life. At present, display devices find a versatile application in everyday life. In particular, in television sets, computer screens, smart phones and tablet computers, dynamic image data transmission occurs via a display. In addition, more intuitive, bi-directional communication using touchscreens has become possible in recent years. Frequent, direct contact wears off the surface of the display. To avoid the wear caused by the direct contact, the display is currently usually coated with a screen protector. For this reason, it is important to be able to attach the screen protector quickly and accurately.

In the commercially available screen protection films, a release film is disposed on one side of the protective film in order to cover an adhesion-promoting layer of the protective film. Only shortly before the protective film adheres to a screen to be protected, the release film is peeled off. The screen protector is often manually applied by the separation film of the screen protector grabbed at one end and is torn off by hand from the protective film. Thereafter, the screen protector is adhered to a screen step by step, with an observation of the gluing process being done only by the human eye. Although the process of applying the screen protector is simple, small errors can lead to inaccurate attachment of the screen protector or to the formation of air bubbles. For smartphones, tablet computers, desktop computers and even small-format TVs, attaching a screen protector is required.

To facilitate the following description, the aforementioned devices are commonly referred to as screened devices, and the display field for displaying images on these devices is referred to as a screen (to be protected).

In order to prevent inaccurate attachment of the screen protector and remaining air bubbles between the screen protector and the screen, a method of attaching a screen protector has been developed in which first the screen protector and the screen are aligned with each other, the release film is not detached yet. Subsequently, the screen protector and one side of the display screen are attached to each other with Tesafilm. When the screen protector is attached to said side of the display screen, the release film is peeled off and the screen protector is adhered to the screen to be protected. However, the method requires a great deal of time and yet can not avoid that when removing the release film, an offset between the screen protector and the display screen is created. In addition, a bubble-free attachment is only possible if the protective film is pressed in the bonding process repeatedly in a reciprocating motion down.

In order to facilitate the attachment of a screen protector, an auxiliary device for applying (attaching) a screen protector has also been developed. The auxiliary device is designed such that a fixed base is combined with a forward and backward movable carrier. For this auxiliary device screen protectors are made with an extended release film. To attach the screen protector, the display device is first attached to the carrier. Subsequently, one end of the extended release sheet of the screen protector is fixed to the fixed base, and the carrier is brought in by a lever for retraction, whereby the release sheet is simultaneously pulled out. The display unit is pushed deep into the fixed base and a laminator in the fixed base thus has the opportunity to press against the screen protector so that the screen protector is properly adhered to the screen to be protected. While this mechanism facilitates the attachment of the screen protector to the user, gluing is performed deep within the fixed base so that the user can not immediately control the gluing process prior to retracting the display device from the base and this may result in inaccurate attachment of the screen protector. Furthermore, the auxiliary device is heavy, whereby the operation of the auxiliary device requires a large amount of force and stowage and transport of the entire auxiliary device are difficult. The custom-made screen protector must be provided with an extended release film so that the release film is longer than the protective film, with the resulting increased consumption of release film material being detrimental to both economy and environmental protection.

Therefore, there is a need on the part of the manufacturer for an easily operable auxiliary device for applying a screen protector which, taking into account the costs, has a simplified construction, a lower weight and lower production costs and enables an accurately fitting attachment of a screen protector.

As in 3 is the main part of the main operating lever 3 through a main force arm 31 formed, of which there is a main body 33 which has a main positioning opening 331 which, in cooperation with a Hauptpositionierteil 333 causes a catch. The two sides of the main arm 31 are one-piece with a main press part 35 connected to that with the screen protector 2 in contact surface as main lamination area 351 referred to as. Further, the two ends of the main power arm 31 each to a pair of pivoting Hauptarretierteilen 37 connected.

The main part of the auxiliary operating lever 5 is by a Hilfskraftarm 51 formed, of which an auxiliary main body 53 extends. The two sides of the auxiliary power arm 51 are one-piece with an auxiliary press 55 connected to that with the screen protector 2 in contact surface as Hilfslaminierbereich 551 which is like the main lamination area 351 is designed as a flat surface. Further, the two ends of the Hilfskraftarms 51 each to a pair of pivotable Hilfsarretierteilen 57 connected.

The following explains the actuation process, which is essentially divided into two stages, namely the installation and the application (attachment). For the process of installing a smartphone 9 will be on 4 directed. First, the smartphone 9 with the screen 91 up in the picture 131 the carrier part 13 placed, taking the picture 131 according to the contour of the smartphone 9 is designed to allow the smartphone 9 exactly fitting in the substrate 1 can be placed. However, it will be understood by one of ordinary skill in the art that the carrier member 13 and the recording 131 may be formed separately, so that the carrier part 13 with different shots 131 for different contours of mobile phones can be combined. To the overall stability of the substrate 1 and into the substrate 1 inserted smartphone 9 It is also possible to increase a heavy base plate 15 at the bottom of the substrate 1 attach to a more stable base for the substrate 1 to provide, thus, a screen protector 2 to assemble efficiently.

For the further steps to assemble the components of the mounting kit is on 3 and 5 directed. The main positioning part 333 is through the speaker recess 22 the screen protector 2 pushed and by a slight pressure to snap into the on the main body 33 made home positioning opening 331 brought, so the screen protector 2 and the main operating lever 3 are stably connected to each other. The other side of the screen protector 2 is on the auxiliary main body 53 of the auxiliary operating lever 5 placed, with the main operating lever 3 and the auxiliary operating lever 5 are now arranged approximately parallel to each other and the pivoting Hauptarretierteile 37 and the pivotable Hilfsarretierteile 57 are arranged opposite one another. Thus, the main operating lever 3 , the auxiliary operating lever 5 and the screen protector 2 provisionally composed.

When the main operating lever 3 , the auxiliary operating lever 5 and the screen protector 2 are temporarily put together, they continue with the smartphone 9 , the substrate 1 and the base plate 15 which were previously assembled, assembled. Now the pivoting main locking parts 37 and the main guide grooves 115 aligned and the pivotable Hilfsarretierteile 57 and the auxiliary guide grooves 117 are aligned simultaneously, as in 10 will be shown. Next are the pivoting Hauparretierteile 37 and the pivotable Hilfsarretierteile 57 at the same time to engage in the main guide grooves 115 and the auxiliary guide grooves 117 brought. Thus, the mounting kit is fully assembled.

When the mounting kit is assembled, applying (attaching) a screen protector 2 performed as in 6 to 11 will be shown. To the initial position and the rest position of the main operating lever 3 and the auxiliary operating lever 5 clearly marked in the phases, the initial position of the operating lever is shown in the figures with a dotted line and the rest position of the operating lever is indicated by a solid line, the Actuating direction is shown with an arrow as a dotted line.

As in 6 is shown, the application process in the first embodiment begins with the operation of the auxiliary operating lever 5 , At the beginning is the auxiliary operating lever 5 in the auxiliary rest position. Now the Hilfskraftarm 51 with the auxiliary locking parts 57 as axes pushed upwards (see 7 ) that the auxiliary operating lever 5 Turn clockwise by more than 90 degrees until the auxiliary press 55 the screen protector 2 lightly touched and this on the screen 91 pushes and sticks, creating a resistance that the auxiliary operating lever 5 into the auxiliary position. If the protective film 24 and the auxiliary release liner 284 together with the auxiliary operating lever 5 be rotated to a large extent, so the auxiliary release film dissolves 284 slowly from the primer layer (not shown), because the surface tension of the auxiliary release film is relatively small and the adhesive force of the primer layer is slightly smaller than the elastic restoring force of the auxiliary release film 284 , wherein this restoring force by bending the auxiliary release film 284 at one to a terminal edge of the screen 91 of the smartphone 9 adjacent location is generated.

If the lower end of the auxiliary release liner 284 from the protective film 24 is solved, the auxiliary operating lever 5 at the fixed angle of the Hilfsbetätigungsstellung slightly pushed down and along the auxiliary guide grooves 117 moved to the left until the pivoting auxiliary locking parts 57 through the auxiliary guide groove outputs 118 completely from the auxiliary guide grooves 117 separate. Thus, the left half of the protective film 24 glued and the auxiliary release liner 284 is completely off the screen protector 2 solved.

Subsequently, the main positioning part is removed from the main positioning hole (not shown), as in FIG 9 will be shown. Now the main operating lever is located 3 at rest and the main arm 31 comes with the pivoting main locking parts 37 as axes pushed up so that the main operating lever 3 Turn counter-clockwise more than 90 degrees until the main part is pressed 35 the protective film 24 lightly touched and this on the screen 91 pushes and sticks, creating a resistance that the main operating lever 3 brings into the main operating position, with the lower end of the main release film 282 now slowly from the protective film 24 separates. If the lower end of the main release film 282 from the protective film 24 is solved, as in 11 is shown, becomes the main operating lever 3 at the fixed angle of the main operating position slightly pushed down and along the main guide grooves 115 moved to the right until the main pivotal locking parts 37 through the main guide groove exits 116 completely from the main guide grooves 115 separate. Thus, the protective film 24 completely attached and the main release liner 282 is completely off the protective film 24 solved. Now the protective film 24 completely on the surface of the screen 91 glued.

If the application process, as in 12 is shown is completed, the protective insulating film 26 by means of the auxiliary release unit 262 subtracted from left to right, so a mint, smooth surface of the protective film 24 is exposed. In this way, a precise and easy application of the protective film 24 allows. Finally, the smartphone 9 through the auxiliary removal opening 135 from the recording 131 taken.

The design of smartphones is constantly changing. Currently, there are screens with rounded edges. 13 and 14 show a second preferred embodiment of the mounting kit according to the invention, wherein the second embodiment is constructed in part exactly as the first embodiment. In the following, only the differences are explained. The edges of the smartphone 9 ' are rounded. At the right side of the screen 91 ' is a speaker unit 911 ' and on the left side of the screen 91 ' is a microphone unit 913 ' provided, reducing the structure and profile of the screen protector used 2 ' , the main operating lever 3 ' and the auxiliary operating lever 5 ' are changed.

To adapt to the rounded edges of the screen 91 ' are the main press 35 ' of the main operating lever 3 ' and the auxiliary press part 55 ' of the auxiliary operating lever 5 ' formed such that they each have a Hauptlaminierbereich 351 ' , an auxiliary lamination area 551 ' , two main undercurrent areas 353 ' and two auxiliary undercone areas 553 ' wherein the main lamination area 351 ' and the auxiliary lamination area 551 ' each have a flat surface, and wherein the two main undercut areas 353 ' and the two auxiliary undercut areas 553 ' on the respective two sides of the main lamination area 351 ' and the auxiliary lamination area 551 ' located and with the rounded edges of the screen 91 ' match. With such a trained Appliziervorrichtung is the application of a screen protector 2 ' on a screen 91 ' facilitated with rounded edges.

In the second embodiment is also on the left side of the screen 91 ' of the smartphone 9 ' a microphone unit 913 ' and on the right side of the screen 91 ' of the smartphone 9 ' a speaker unit 911 ' arranged. That is why on the left and right side of the Screen protective film 2 ' in each case a corresponding microphone recess 23 ' and a corresponding speaker recess 22 ' educated. Characterized in that both on the main side and on the auxiliary side of the Appliziervorrichtung different reference positioning points are present, the positioning can be designed in a simplified manner that the Hauptpositionierteil 333 ' directly from the main body 33 ' extends. Furthermore, an auxiliary positioning part extends 533 ' from the auxiliary main body 53 ' , wherein the Hilfsositionierteil 533 ' opposite the microphone recess 23 ' is arranged.

The structural differences also result in differences in the actuation process of the second embodiment. As previously described and in 5 is shown in the first embodiment, the main operating lever 5 , the auxiliary operating lever 5 and the screen protector 2 by locking the main positioning part 333 in the main positioning hole 331 provisionally composed. Then the other side of the screen protector 2 only on the auxiliary main body 53 of the auxiliary operating lever 5 be placed. In the second embodiment (see 13 ) are on the left and right sides of the screen protector 2 ' one microphone recess each 23 ' or a speaker recess 22 ' arranged so that before putting the screen protector together 2 ' with the main operating lever 3 ' and the auxiliary operating lever 5 ' First, the relative arrangement of the recesses must be determined to the positioning. After that, the screen protector 2 ' positioned so that the microphone recess 23 ' around the auxiliary positioning part 533. ' is arranged around and the speaker recess 22 ' around the main positioning part 333 ' runs around. A slight pressure turns the screen protector 2 ' attached. Thus, the main operating lever 3 ' , the auxiliary operating lever 5 ' and the screen protector 2 ' provisionally composed.

For the subsequent application process is on 6 to 11 the application process in the mounting kit of the second embodiment is similar to the Appliziervorgang with the mounting kit of the first embodiment. In the second embodiment, since there are reference positioning points on both the main side and the auxiliary side of the applicator, the timing of operation of the main operating lever is 3 ' and the auxiliary operating lever 5 ' not fixed and restricted and can be determined by the user. However, with the operation lever which is operated first, a complete application process must first be performed before the application process is performed on the other side.

The embodiments described above are practical enough for some operators of a shop for screen protectors and also allow the end user to easily install a screen protector, with neither the labor nor the cost of the mounting kit is large. However, operators who professionally and massively install screen protectors for customers on screens prefer that the main operating lever and the assist operating lever never be separated from the substrate and thus easily reset immediately after a screen protect film application operation.

For the third preferred embodiment of the invention is on 15 directed. In the third embodiment, the main operating lever 3 '' a main reset device, which with the pivotal main locking parts 37 '' For example, the main reset device herein is a main spring 39 '' is.

Furthermore, the main operating lever rotates 3 '' clockwise until it returns to its original home position. Of course, the auxiliary operating lever 5 '' also an auxiliary spring 59 '' on, the same as the mainspring 39 '' works, with the auxiliary spring 59 '' to the pivotable auxiliary locking parts 57 '' connected. By doing that, the main spring 39 '' and the auxiliary spring 59 '' to the main operating lever 3 '' and the auxiliary operating lever 5 '' may be the main operating lever 3 '' and the auxiliary operating lever 5 '' not from the substrate 1'' be separated so that the main guide grooves 115 '' and the auxiliary guide grooves 117 '' unlike the previous embodiments are not provided with main and auxiliary guide groove outputs and are therefore designed as a closed guide grooves.

Furthermore, the substrate 1'' in the third embodiment, in a heavier metal base (not marked with a reference numeral) to enable more stable operation to the professional operators who frequently perform the application of a screen protector. Since different manufacturers' mobile phones or tablet computers have different screen dimensions and contours, several different substrates for the different standards of the manufacturers are interchangeably attached to the metal base, so that the professional operators only need a metal base which interacts with the substrates in different ways Dimensions can be used, whereby a flexible and user-friendly execution of the attachment of a screen protector is realized.

For the fourth preferred embodiment of the invention is on 16 referenced, wherein the construction and the operation of the fourth embodiment for the most part correspond to those of the first preferred embodiment. In the following, only the differences are explained.
